33-multi-keyboard-layouts.patch: Work around strange libxklavier behaviour
(which returns NULL for empty variants, but does not accept NULL when
setting a configuration). This fixes broken variant setting in some cases.
(LP: #550887)

* debian/patches/31-unify-power-strings.patch:
- drop the change for lucid it requires documentation update
which has not been taken into account there, similar changes are done on
the other desktop components too now
